MACHINERY FOR MANUFACTURING'CHEESE.

SPECIFICATION formingpart of Letters Patent No. 239,027, dated March 22, 1881. Application filed July 12, 1880. (No model.) Patented in Canada January 22, 1880.

To all whom it may concern:

Be it known that I, ARoHrBALn H. BRINT- NELL, of the city of Belleville, in the county of Hastings and Province of Ontario, Canada, have invented certain new and useful Improvements in Machinery for Manufacturing Cheese; and I do hereby declare that the following is a full, clear, and exact description of the same, which will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in mechanism for manufacturing cheese; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan, Fig. 2 a longitudinal section, and Figs. 3 and 4t cross-sections, of machinery embodying my improvements.

A is a curd-vat, constructed and heated by steam in the usual manner, and B is a sink placed in connection with the vat at a lower level, and arranged to receive the contents of the vat by gravitation through the pipe A. A number of these vats and sinks are placed in a row, with a suitable space between each set for the movement of operators and inspection. Above each vat a frame, G, is built, on which is mounted a series of upright shafts, 0, which are rotated simultaneously and at equal speed by means of the pulleys O 0 belt 0 and connecting-bar O as shown, or in any other suitable manner. Each of the upright shafts is provided with a cross-beam, D, to which is attached a pair of adjustable agitators, D. These agitators are pivoted at their upper ends to the cross-beam, provision being made, by means of a slot, 8, and the pivotal bolt 6, screw-thread ed at one end and provided with a nut, to allow of vertical adjustment,and at their lower ends are provided with a broad curved blade, 01, which is immersed in the curds, and as the shafts rotate stir and break up the contents of the vats in a very efficient and expeditious manner. The mechanism of each vat is driven from a main-line shafting, E, by means of the counter-shaft F, gearing F, bevel-gears F F, and shaft F and to provide a means for throwing the mechanism out of operation, one end of the shaft F,supported in the frame F is connected to a slotted wed ge, f, by the proper movement of which the gearwheels F can be placed out of contact and themotion of the vat machinery arrested, when desired, without stopping the line-shaft or in terfering with the operations in the remaining vats or in the sinks.

The sink B is of peculiar constructiomheing circular in form, and provided with a well, B, in the center of the bottom of which is placed a strainer, B This strainer projects upwardly from the bottom of the sink in a slightly conical form, and is closed at the upper end. The strainer may be constructed of sheet metal provided with perforations, as shown, or may be made of wire-cloth or other suitable material,

- which will allow of the proper discharge of the whey from the sink without allowing the solid matter to escape.

J is a sink-agitator, having three (more or less) arms, J, to each of which are attached the teeth K. These teeth are made adjustable on and detachable from thearms, and each tooth is provided with a number of outwardlyprojecting spurs, 70, which are designed to break up or cut the matter in the sink with great thoroughness. The agitator is attached to a vertical shaft, L, which is driven from the main-line shaftin g by the bevel-gearing L L and for the purpose of allowing the sink mechanism to be put out of operation, when desired, the beam M, which supports the shaft and wheel L, is provided with a cam-plate,M, so that the teeth of the bevel-wheels can be thrown in and out of gear at pleasure. Thus it will be seen that all the vat and sink mech anism can be run simultaneously from a single line-shaft, or individual sets can be operated or thrown out of. gear, or a vat or sink mechanism can be operated independently of the remainder of the plant at pleasure. The agitators in the vats are arranged so that they may be turned up or withdrawn from the conmoving the bolts 6, which secure them to the cross-beams D.

The advantages of my improvements are, that the operations of preparin g the curds in cheesemaking, now so largely dependent on manual labor, is efficiently and rapidly performed by machinery in a cheap, clean. and satisfactory manner.

If desired, the vat and agitator can be employed in creameries for the manufacture of butter with advantage, as the agitation caused by the paddles is very conducive to the rapid formation of butter.

In operation, after the curds are formed in the vats in the usual way, and allowed to stand undisturbed a sutticientlength of time, and after the curds are cut, as usual, the agitators are introduced into the mass, and, being placed in motion, rapidly induce the congealed curds to the consistency required. After this opera, tion is performed the mass is drawn off into the sink through the spout at the end of the vat, or by a siphon, if preferred. Here the whey is separated from the solid portion of the mass, and passed off through the strainer-well and connecting-pipes, the action of the rotating teeth, with their spurs, performing the work of separation with great efficiency and rapidity.

I claim as myinvention and desire to-secure by Letters Patent 1. The combination, with the vat A, of the frame 0, shafts C, agitators D, pulleys G connecting-rods G with its cranks, and belt 0 whereby a rotary motion is imparted to the agitators, substantially as described.

2. The combination, with the revolving sinkagitator J, having arms J, with teeth K, of the "ertical shaft L, horizontal shaft E, bevel-gears L L frame F beam M, and cam-plate M, substantially as described, and for the purpose set forth.

3. The combination, with the shaft E, counter-shaft F, double slotted frame F and mechanism, substantially as described, for operatin g the agitators, of the wedge f, pivoted to a lever, and provided with an inclined slot carryin g one end of the counter-shaft F, substantially as described, whereby the gear-Wheels of a vat can be disengaged and the rotation of its agitators arrested, when desired, without interfering with the rotation of the agitators in the other vats, as specified.

4. The combination, with the curd-vat A, provided with an outlet, A, leading into the sink, of the sink B, provided with the strainer B, agitators D, stirrers K, and mechanism, substantially as described, whereby the agitators and stirrers are revolved, substantially as described, and for the purpose set forth.

5. The combination, with the curd-vat A, provided with an outlet, A, leading into the sink, of the sink B, provided with the strainer B, agitators D, stirrers K, beam M, provided with the shipping cam-plate M, and mechanism, substantially as described, for revolving the agitators and stirrers, whereby said agitators and stirrers are simultaneously revolved or the agitators only revolved, substantially as described.
